Equine Leptospirosis

Wednesday, December 6, 2017

(NY) Equine Leptospirosis abortion was presumptively diagnosed based upon extremely elevated titers on the Lepto MAT test acutely (L. pomona ≥ 12,800) and histologic placentitis. Leptospira were not detected by PCR of the placenta and no organisms were observed on histopathological examination. Testing for other infectious causes of equine abortion were unremarkable. Convalescent serology is pending and an update will follow.
Update: Lepto PCR was added to lung tissue from the fetus and was positive at the Moderate level, confirming this as a Leptospirosis abortion.
